Click the button 5x to turn it on and off. The button controls all the functions and features the Signal LED light. Click it 3x to change your voltage level; each level has a different color light. 2.7V is yellow, 3.2V is green, and 4.0V is red. Different terpenes release their flavors at different temperatures, so we recommend trying the different voltages with each new strain you bring home!
